CAN AND MEANS FOR CLOSING SAME.

SPECIFICATION forming part of Letters Patent No. 5,614, dated August '7, 1900.

Application filed June 25,1900.

To all whom it may concern-.-

Be it known that I, GEoRoE H. DUNBAR, a citizen of the United States, residing at New Orleans, in the parish of Orleans and State of Louisiana, have invented new and useful Improvements in Cans and Means for Closing Same, of which the following is a specification.

My invention relates to improvements in cans and means for closing cans, and has for its object to provide a novel and simple closure for a can provided in its head with a filling-mouth, the closure means adapted to be provided with a pouring-opening and all so arranged that liquids of a nature which will deteriorate by continuous exposure .to the airsuch as molasses, paints, oils, &c.- may be contained therein, the pouring-aperture opening from time to time, as may be desired, to withdraw the contents from the can and the cover replaced to close the pouring-aperture and hold the contents in practical hermetic sealing or air exclusion.

To the ends stated my invention consists in a can and its closing means constructed as hereinafter set forth and claimed, reference being had to the accompanying drawings, in which- Figure 1 is a central vertical section of a can constructed in accordance with my invention and illustrating in connection therewith the closing means, the two elements of which are separated. Fig. 2 is an enlarged sectional view of the top of the can with the closing means assembled; Fig. 3, a similar view, on an enlarged scale, illustrating the position of the parts when the removal of the removable and replaceable cover has been initiated. Fig. 4. is a top plan view of the can, illustrating the filling-mouth before the closure has been applied thereto; Fig. 5, a similar view of the can with the closure completed in proper position in the can-head.

In the said drawings the reference-numeral 1 indicates the can-body, which is of ordinary or usual construction and is provided with a Serial No. 21,528. (No model.)

ing the body and the top shipped separately, the latter to be secured to the body by the can-filler after the can has been filled. In the top 2 is formed a filling-mouth 3, through which the can may be filled by the packer'or at the filling establishment, and a groove 4 is formed around the filling-mouth, as shown, leaving the wall of the opening slightly upstanding in the form of a lip 5. This opening is closed by a dished cap 6, the rim of which is provided with a horizontal ledge 7 and a depending lip 8 to lit the groove l, in which it is soldered, as illustrated at 9. The body or dished part of the cap 6 depends into the filling-mouth of the can, and it is intended that it shall be soldered to close the filling-mouth after the can has been filled and to have the bottom of the dished part out out for the purpose of providing an opening through which .the contents of the can may be poured from time to time for use, and to facilitate the cutting out of the bottom I provide therein a groove or score 10.

Many liquidssuch as molasses,paints,oils, &c.if left remaining in the'can after the pouring-orifice has been formed in the cap 6 will deteriorate or spoil, and to prevent this and preserve the contents in good condition I provide a removable and replaceable prycover 11, which is, with the exception of the downwardly-extending lip 8, a duplicate on a slightly-smaller scale of the cap 6, having a dished bottom 12 and a laterally-extending horizontal flange 13, which rests upon the horizontal ledge 7 of the cap 6, as shown, and the side wall 14 of its dished body fits snugly against the interior face of the corresponding wall 15 of the cap 6, the fit being such that it willrequire manual force to remove the prycover and such that when said cover is fitted in place in the cap 6 there is a practical exclusion of air. As will be seen, the dished bottom of the pry-cover 11 rests throughout its extent upon and is supported by the bottom of the cap 6, so as to preserve the prycover from indentation or distortion or other injury While it is in its place to serve as a closure to the pouring-opening. As Will be seen, a slight space exists between the under surface of the flange 13 of the pry-cover 11 and the depending lip 7 of the cap 6, and also the edge of said flange extends slightly beyond the horizontal ledge of the cap, as shown at 16, whereby there is presented an entrance for the insertion of an instrument,whioh need not necessarily be a sharp one, as a blunt instrument will .serve equally as well, by the use of which the cover may be pried up and removed from its seat in the cap 6. The initial stage of such prying up is shown at the left in Fig. 3 of the drawings.

By my inven tion I provide a novel and very simple closure for cans which may readily be assembled in the filling-mouth of the can after the latter has been filled and in the cap forming an element of ,which provision to facilitate the cutting out of the pouring-opening is made and embodyinga removable and replaceable pry-cover, of dish shape, corresponding to that of the cap and in which it is seated with its dished bottom resting upon and supported by the bottom of the cap, with the flange of the pry-cover so formed and arranged with relation to the cap as to extend slightly beyond the horizontal ledge thereof and present a space for the insertion of an instrument beneath said flange, whereby the cover may be readily removed by prying it from its seat in the cap. This arrangement is novel, very simple, and economical and easy of manufacture, composed as it is of few and simple elements, and in use is very satisfactory.

Having thus described my invention, what I claim is- 1. The combination with a can having a filling-mouth formed in its head, of a dished cap depending into said mouth and adapted to be soldered to the can-head to cover the fillingopening, and the bottom of which is adapted to be cut out to provide a pouring-opening, and a dished pry-cover adapted to seat snugly in the cap with its bottom resting upon and supported by the bottom of the latter, said pry-cover provided with a flange beneath which an instrument may be inserted and the cover pried out, substantially as described.

2. The combination with a can having a filling-mouth provided in its head, and a groove surrounding said opening, of a dished cap, the lip of which is constructed to seat in said groove and the dished body of which depends into the filling-mouth, the bottom of said cap provided with means for facilitating the cutting of the pouring-opening therein, and a dished pry-cover, the dished body of which fits snugly in the dished portion of the cap, with its bottom resting upon and supported by the bottom of said cap, and a flange on said pry-cover resting upon the ledge of the cap and arranged for the insertion of an instrument beneath said flange for prying the cover out, substantially as described.

3. The combination with a can provided with a filling-mouth in its top, and a groove around said opening, of a dished cap provided with a rim having a horizontal ledge and continuing in a downwardly-extending lip seated in said groove and adapted to be soldered therein, and a dished pry-cover seated in said cap provided with a flange resting upon the horizontal lip of the rim of the cap and extending slightly beyond such portion whereby a space is provided for the insertion of an instrument beneath said flange to pry the cover out, substantially as described. 7

4. The combination with a can provided with a filling-mouth in its top, and a groove around said opening, of a dished cap provided with a rim having a horizontal ledge and continuing in a downwardly-extending lip seated in said groove and adapted to be soldered therein, and a dished pry-cover'seated in the dished portion of the cap with its bottom resting upon and supported by the bottom of said cap and provided with a flange resting upon the horizontal ledge of the rim of the cap and extending slightly beyond such portion, whereby a space is provided for the insertion of an instru ment beneath said flange to pry the cover out, substantially as described.

In testimony whereof I have hereunto set my hand in presence of two subscribing witnesses.
